In construction
YALI® is a lightweight, natural pozzolanic product with an excellent CO² footprint and is an ideal additive for cement- and lime-bound products. YALI® is also used as pure natural granules in mortars and renders and in road construction.
In Europe, the United States of America and the Arab states, the outstanding properties of YALI® are used to manufacture high-quality building products that meet international standards and the requirements of modern construction.
YALI® is a pure natural product free from organic and inorganic contaminants
YALI® provides insulation, is resistant to heat and frost, does not burn or smoulder and, thanks to its white colour, can also be used in exposed masonry.
YALI® releases no hazardous emissions, is fully recyclable and poses no hazard to water.

In industry
YALI® can be used for finishing textiles, polishing stone products and metal, and in the chemical and pharmaceutical industries.
YALI® in everyday life
Jeans and fabrics of all kinds can be washed with YALI® to make them supple; marble and granite surfaces can be treated with YALI®, while cosmetics and toothpastes can contain YALI® to maximise their care effect.
In agriculture
Agriculture
YALI® is a chemically inert material with a neutral pH and low electrical conductivity. This makes YALI® an ideal inorganic component for substrate layers and can optimise your production. For this reason, YALI® is successfully used in applications such as plant cultivation. YALI® is particularly suitable for agriculture because of the following properties:
- free from inorganic and organic contaminants,
- consistent particle size fractions,
- long-term performance,
- low costs and
- abundant availability.
Horticulture
YALI® is used as a substrate layer in horticulture and landscaping, for example in:
- hydroponic vegetable cultivation, such as tomatoes, aubergines, cucumbers, melons, etc.
- hydroponic flower cultivation, such as roses, daisies, etc.
- cultivation of potted plants.
- nurseries for raising plant seedlings.
YALI® is a pure natural product free from organic or inorganic contaminants that ensures adequate aeration and water supply to plant root systems when appropriate irrigation methods are used.
Green roofs
Its low particle density, uniform particle size distribution, chemical purity and stability, particularly under frost and high external pressure, make YALI® very well suited as an aggregate for green roofs.
In geotechnical engineering
Lightweight fill material
YALI® is a pure natural product whose physical, chemical and mechanical properties make it an ideal lightweight fill material for numerous geotechnical applications.
Properties of YALI®:
- Bulk density, particle density and particle strength
Depending on the grading, the bulk density of dry YALI® (105° /24 hours) ranges from 650 kg/m3 to 830 kg/m3, the average particle density is between 0,98 and 1,01, and the average particle strength is 21,2 kN. These properties reduce loads and lateral stresses, minimise transport costs and facilitate handling. Thanks to its excellent thermal insulation properties, YALI® provides protection against extreme temperature fluctuations. - High angle of internal friction
YALI® is available with a uniform particle size distribution, a property that, together with its high angle of internal friction, increases the cohesion and stability of the product without the need to add mineral materials. - Chemical inertness
YALI® is resistant to frost and heat, does not corrode and is not subject to chemical attack. It also has pozzolanic properties.
Uses
These outstanding properties of YALI® are used in the United States, Europe, the Mediterranean region and the Arabian Peninsula, where it serves as lightweight fill material in a wide range of geotechnical applications, for example:
- road paving,
- road and path construction,
- harbour construction,
- bridge construction and
- embankment construction.
YALI® has proved to be a highly versatile and competitive material, providing solutions for challenging land filling and slope conditions.
The properties of YALI® become particularly important on soft or unstable ground, for example in road and hydraulic engineering, to reduce loads and prevent landslides. YALI® is therefore particularly suitable in road construction for creating surfaces with high load-bearing capacity for roads and building plots on soft, wet ground.
